Chatting with the hosts of the Australian show "Sunrise" during an appearance on Tuesday, Katy recalled what happened after Miley motioned to her to come close for a KissCam-broadcast smooch during "I Adore You" that night.

"I just walked up to her to give her like a friendly girly kiss, you know, as girls do, and then she like tried to move her head and go deeper and I pulled away," she said, (via E!). "God knows where that tongue has been," she added. "We don't know! That tongue is so infamous!"
